摘要
采用DSA电极电催化处理变性木薯淀粉生产综合废水，研究了槽电压，电流密度，支持电解质，pH值，电解时间等因素对其中COD去除率的影响。在选定的实验条件下，槽电压8V，电流密度为40mA／cm^3，支持电解质为0．1g／L的NaCl，pH值为8．5～9．0，电解2h，废水中COD的去除率达88．3％。
The eletrocatalytic oxidation method with dimensionally stable anode electrode was used to degrade the pollutants（COD） in the producing wastewater of modified tapioca starch. The effects of cell voltage, current density, supporting electrolyte, pH value and electrolysis time on the removal efficiency of COD were studied. Under selected experimental conditions ： cell voltage 8 V,current density 40 mA/cm^2 , concentrationg of sodium chloride 0. 1 g/L, pH value 8.5 - 9.0, electrolysis time 2 h, the removal efficiency of the COD in the producing wastewater of modified tapioca starch is about 88.3% .
